Haven't touched the core classes, so I'm a little dumbfounded as to why it would be crashing on a vanilla command. I'm assuming I've done something stupid with incorrectly registering my own, custom commands, but I'd appreciate some guidance here. It's a minor bug, but it is also one that crashes the game so... I'd like to get it worked out.

Have a modding question? PM me and hopefully I'll be able to help. Good at 2d Pixel Art? We need your help!  http://www.minecraftforum.net/topic/1806355-looking-for-2d-pixel-artist/

Correct. Now, unless we see what you have done, there is not much we can do to correct the problem.

Posted

Hrm. I'll try.

 

 

 

ServerCommandManager scm = (ServerCommandManager) event.getServer().getCommandManager();

scm.registerCommand(new CommandCheckInventory());

scm.registerCommand(new CommandCheckChests());

scm.registerCommand(new CommandCreateShape());

scm.registerCommand(new CommandACS());

scm.registerCommand(new CommandEconomy());

scm.registerCommand(new CommandSpecializations());

scm.registerCommand(new CommandCustomChat());

 

 

And all of the commands are empty copies of this:

 

public class CommandSpecializations extends CommandBase

{

    public String getCommandName()

    {

        return "scm";

    }

   

    public void processCommand(ICommandSender par1ICommandSender, String[] par2ArrayOfStr)

    {

    }

   

    @Override

public boolean canCommandSenderUseCommand(ICommandSender icommandsender)

    {

    return true;

    }

   

    @Override

    public int getRequiredPermissionLevel()

    {

        return 0;

    }

 

@Override

public String getCommandUsage(ICommandSender icommandsender) {

// TODO Auto-generated method stub

return null;

}

}

 

 

 

Except replace 'scm' with each commands unique tag, including (in order): "checkinv", "checkchests", "createshape", "acs", "econ", "scm", "ccs"

 

All of the actual command logic is handled in a CommandEvent handler class, where I check to see which command it is by using "event.command instanceof CommandSpecializations" as an example. Obviously all of the others are the same but... that's about all that the commands do. Besides "/help" all of the commands I have work.

Scratch that, just looked at the new method required by commands. I'm willing to bet the '/help' command uses "public String getCommandUsage(ICommandSender icommandsender)" to populate its list- and since mine returns null, it causes an error.

 

Just ran it and tried the command- it works fine now. Issue resolved. :)

That was what I expected, since help would trigger a usage event and it would not like to see null. Glad you figured it out.

    • I can't understand the logs, so I'm hoping someone could tell me what's causing the issues. https://pastebin.com/d1XPxCes
    • Hello I'm currently making an Item that thrusts you to viewing direction, and I referenced riptide code of trident for my item. @Override public InteractionResultHolder<ItemStack> use(Level pLevel, Player pPlayer, InteractionHand pUsedHand) { if(!pLevel.isClientSide() && pUsedHand == InteractionHand.MAIN_HAND && pPlayer.isOnGround()){ Impale(pPlayer, pUsedHand); pPlayer.getCooldowns().addCooldown(this, 40); } return super.use(pLevel, pPlayer, pUsedHand); } public void Impale(Player pPlayer, InteractionHand pUsedHand) { float playerYRot = pPlayer.getYRot(); float xForce = -Mth.sin(playerYRot * ((float)Math.PI / 180F)) * Mth.cos((float)Math.PI / 180F); float yForce = 100.6F; float zForce = Mth.cos(playerYRot * ((float)Math.PI / 180F)) * Mth.cos((float)Math.PI / 180F); float stabilizedForce = Mth.sqrt(xForce * xForce + zForce * zForce); xForce /= stabilizedForce; zForce /= stabilizedForce; pPlayer.push((double)xForce, (double)yForce, (double)zForce); pPlayer.sendSystemMessage(Component.literal(playerYRot + " " + xForce + " " + yForce + " " + zForce + " " + stabilizedForce + "shoo")); } I sure edited a lot from source code but this isn't working somehow? the sendSystemMessage works correctly. It prints value of variables and string, but the force isn't applying to player. how can I make this to work? Thanks.
    • i tried putting a modpack together and cant get this working no matter what i have tried log: https://pastebin.com/uqz1aKiY
    • We have an event for an Entity being struck by lighting, but doesn't look like we have one for Blocks. And unfortunately, looking at it, the LightingBolt entity doesn't have any context on why it was registered, so you wouldn't be able to get the source context. What are you trying to accomplish with this event?
    • Hey guys, I'm trying to use the simple planes mod https://www.curseforge.com/minecraft/mc-mods/simple-planes with a nuclear bombs mod https://www.curseforge.com/minecraft/mc-mods/nuclear-bombs . The simple planes mod has a cargo plane that can drop tnt, and i want it to work with the nuclear bombs. I added this JSON file from chatGPT to the payloads folder in simple planes (because the nukes couldn't even get stored in the plane in the first place), but this only allows the nuke to drop but doesn't explode: https://mclo.gs/3uEQIX2 . This nuke mod requires a redstone signal and then manual activation, which makes this tougher i imagine. If someone could write me a code for the payload folder for simpleplanes, something that even tampers with the nuke mod, or any general suggestions that would be great!  Many Thanks
